Clench your glutes and ready your weapons, actionistas! The latter-day tale of "Hansel & Gretel: Witch Hunters"—you know, the bit that comes after those precious wee house-eating, crone-killing children grow up—is coming to theaters this Friday, January 25. And today, we've got a delicious After Hours treat courtesy of MTV News' Josh Horowitz: stars Jeremy Renner and Gemma Arterton, here to teach us all they know about the business of being a badass.

If you've ever yearned to know the true meaning of badassery, just watch and learn about all things butt-stomping from the masters. For instance, did you know that true badasses learn their ass-badness from an early age? In Gemma's case, she uncovered her destiny as a 13-year-old clubgoer, when, as she recalls, "This guy pinched my butt, and I punched him in the face!"

So. Bad. ASS.

Jeremy, meanwhile, was both humble and vague when asked to instruct on the finer points of badassery.

Other badass must-haves include outfits made of leather (Gemma: "It looks good on a bad ass!") and weapons—but don't give your gun a cutesy name like "Spike" or "Polly." According to Jeremy, being a real badass means that "there's no tomfoolery. It is what it is."

Also a badass trait: using the word "tomfoolery" in a sentence. Which...hey! We just did it! Hooray! Next stop: heavy artillery and tight leather underpants. YES.

What did you take away from this excellently badass episode of After Hours?
